Distribution

The range of the mastiff bat, or Eumops bonariensis, extends from Veracruz, Mexico, through Central America and into South America. In southern South America mastiff bats are found throughout Paraguay, sections of Uruguay, and as far south as the Buenos Aires province in Argentina. Mastiff bats have only been found in the lowlands throughout this range. (Redford and Eisenburg 1992, Reid 1997)
